N.C. Department of Transportation crews recently conducted several tests and surveys of the Herbert C. Bonner Bridge on N.C. 12 over the Oregon Inlet in Dare County.
These tests allowed the department to gather crucial information to help evaluate the overall effectiveness of the sand placed in the area where erosion occurred and determine the next steps for repairs.
Approximately 30,000 cubic yards of sand were pumped from the main navigation channel of the Oregon Inlet to the location at Bent 166 underneath the Bonner Bridge where scour, or the erosion of sand from bridge pilings, caused NCDOT to close the bridge on Tuesday, Dec. 3.
